*** Edited by Staff to clarify the topic title. Please put as much info in the title as possible; they are crucial.  ***Hi All, Requesting some assistance and/or opinions here. I have another example Lincoln Cent with silverish (likely underlying zinc) areas on both the obverse and reverse. From my online research of similar examples, this would typically be called a " Dryer Coin". However, I am not understanding how turning/rolling, or caught in a dryer groove could cause this pattern of "damage". The obverse has a silver strip around the outside of the coin, but it appears to have a raised lip on both sides of the strip. See the pic with the silver strip next to the date. If this coin was stuck in a dryer groove, I would expect to see more severe scratches somewhere. The obverse has other silver areas at bottom of bust and one spot above the ear. The reverse shows the silver areas on the memorial and most of the One Cent letters. The rest of the reverse appears intact including the rim. I don't see how these patterns could be caused by a dryer. The physical characteristics are normal except the thickness; Weight = 2.49 g, Diameter = 19.02, Thickness = 1.39 mm. What is a reasonable explanation for these patterns?

 To CCF! It's PMD of some sort. Could have been sanded down. Who knows. Whatever happened to it, it's not a mint error.

to the CCF You're right, it is not a Dryer Coin. The surface has been sanded or ground down. Either intentionally or not, it is still considered damage.

There are a dozen different possible explanations for such damage occurring. Someone carefully buffing away at the coin using a dremel, for example. Or perhaps someone simply rubbing the penny back and forth on a piece of paper for hours. Or maybe it simply got stuck in some kind of coin-counting machinery for years. We weren't there to watch it happen, so we can't really know for sure.

Exposed zinc will start to rot away the coin into dust.

Hi All,
Thanks for the welcome note and thanks for all the opinions, I appreciate it
Unfortunately, I can't seem to get my brain wrapped around the idea of it being ground or sanded down. It seems to "clean" in the silver areas, and overall. I would expect that any rough handling or grinding/sandling, intentional or not, would cause very visible scratches or other digs and dings. I guess I will file this one in the UCP bin. (Unexplained Coin Phenomena). lol
Cheers!

(Unexplained Coin Phenomena) Ground down, sanded down, etc. are just generic terms. Unless you were there at the time, you may never know exactly how the damaged happened. The only thing that really matters is that it could not occur when the coin was struck so it is PMD.

Keep in mind this cent has bee around the block a time or two...(like 35 years)

Are some pennies rims that large? Or would that result from the damage?

The obv. rim has been sanded down exposing the zinc core ( that is the grey color) also making an illusion that the rim is wider than what it should be.
